You may be able to make a request to the US Department of State for your records. I'd make it clear in your request that you're requesting your DS-160 specifically.
It's a fairly convoluted process: you'll have to draft your own request letter that complies with their requirements, and the website seems to be indicating that the only way to get it to them is to send it in by postal mail or fax. The wait for a response, especially given the pandemic, could potentially be extremely lengthy.
