TT asked me to review my federal refund when I was almost done. Turns out TT had deleted a bunch of fields that had already been filled in automatically without my input.

I was asked to review my federal refund, and when it did TurboTax had deleted a bunch of fields that were previously automatically filled out. Before it asked me to review I had about $1800 tax owed and now after I manually typed in all the same values again it suddenly says I have $28,260 in taxes due?!?!? What happened here?
