2020 Form 6252 S corporation line 22 not calculating

[jayhasthemoney]

I have a prior year installment sale.  Line 22 is not adding line 20 and 21 in Part II... Is there a way to override or fix this?  I have $0 on line 20 and $8,648 on line 21 but line 22 is $0 and it should add line 20 and line 21.

I got it, had to take it out and put it in again?
