The problem I was having was that the program was populating my (spouse's) amount with what looks like a random number rather than the proportion that should be allotted to me, imported/calculated from the 2019 tax return. I think what happened was that we had a net loss on a rental property in 2019, which gave my husband a negative income. I don't think TurboTax knew how to handle that. I made the entries manually. I would caution others to double check what's being imported and not just take for granted that it's accurate!
