Just wanted to reply to this, as I had the same problem and came across this as I was looking at how to solve it and figured it out at least on my end. I entered my income (Crypto Mining) as 1099k as was suggested above but kept getting at the end that I had to review, and there was no EIN number on my 1099-NEC worksheet. I guess going through the questions a worksheet for a 1099-NEC was added to my return and being there it needs the number. Just go on the left hand side and select Tax Tools, then Tools, then select I'd like to delete a form. Find the 1099-NEC worksheet and delete them. That doesn't affect any money entered into your 1099k, at least it didn't for mine. After that it should get rid of the error since the worksheet isn't there needing the number, which it shouldn't be since you are not using it.
