This is an error on TTO side. Can you delete the 1099-S and re-enter? Other option would be to download Desktop which is cheaper and go into the gain exclusion worksheet and correct question 14. The question is Did you or your spouse if filing jointly own and use the property as your main home for a total of at least 2 years of the 5-year period before the sale?
I walked thru the interview questions twice and the error cleared.
