It was definitely said. There was no joke, hint of a joke, smirk, or any other indication that he was being facetious in his official press conference.

US President Donald Trump has been lambasted by the medical community after suggesting research into whether coronavirus might be treated by injecting disinfectant into the body.
He also appeared to propose irradiating patients' bodies with UV light, an idea dismissed by a doctor at the briefing.
Another of his officials had moments earlier said sunlight and disinfectant were known to kill the infection.
"So, supposing we hit the body with a tremendous - whether it's ultraviolet or just very powerful light," the president said, turning to Dr Deborah Birx, the White House coronavirus response co-ordinator, "and I think you said that hasn't been checked but you're going to test it.
"And then I said, supposing you brought the light inside of the body, which you can do either through the skin or in some other way. And I think you said you're going to test that too. Sounds interesting," the president continued.
"And then I see the disinfectant where it knocks it out in a minute. One minute. And is there a way we can do something like that, by injection inside or almost a cleaning?
"So it'd be interesting to check that."
Pointing to his head, Mr Trump went on: "I'm not a doctor. But I'm, like, a person that has a good you-know-what."
He turned again to Dr Birx and asked if she had ever heard of using "the heat and the light" to treat coronavirus.
"Not as a treatment," Dr Birx said. "I mean, certainly, fever is a good thing. When you have a fever, it helps your body respond. But I've not seen heat or light."
"I think it's a great thing to look at," Mr Trump said.
If he decided to walk back the statements or imply that he was joking after the fact....then that is yet another example of his incompetence and dangerously stupid way of handling the pandemic. His cult (the republican party as a whole) believes what he says. That's why we saw a rise of disinfectant poisoning soon after his conference:

What’s key is what happened in the weeks that followed Trump’s controversial and widely debunked comments—and there does appear to have been a rise in accidental poisonings thereafter.What’s key is what happened in the weeks that followed Trump’s controversial and widely debunked comments—and there does appear to have been a rise in accidental poisonings thereafter.
In January, February and March of 2020, accidental poisonings with household disinfectants were up 5%, 17% and 93% respectively over the same months in 2019. In April, which includes an eight day period from the 23rd of the month to the 30th, following Trump’s comments, the increase was 121% compared to April of 2019. In the first ten days of May, things settled down some, with poisonings up 69% over the same 10-day period in 2019.
For bleach, the numbers are less dramatic, but still telling. In January, February and March 2020 poisonings were up 7%, 1% and 59% respectively over each of the same months last year. In April they leapt 77%. As with disinfectants, May has similarly improved a bit, with the first ten-day period showing an increase of 51% over the same 10 days last year.
But I'm sure you'll respond with clear evidence and sound reasoning to support your claim....
