THIS SAME THING HAPPENED TO ME and is currently happening. I claimed my childcare the last two years and it didn't affect my return, I just thought maybe it wasn't a write off. This year when I added it, it added over $2,000 to my return, however my husband made slightly less so I took it off mine and added it to his- which it did absolutely nothing, no impact on the return and his return was absolutely abysmal for the amount he made. I just spent an hour on hold and they couldn't help me, said it is normal for it to be listed in the summary as $0 even though I had all of the receipts listed.
I absolutely do not trust this software anymore and the help center was not helpful. They told me I could pay to contact a tax professional and there was nothing else they could do. It will be the last year I file mine with them and am shopping around for someone else to do my husband's.
