It looks like an issue with TurboTax, the software wants you to put exact amount from each Letter 6419, but round up the amount of each line, before sums it up, which is wrong.
I did summited my return with the "wrong" autogenerated total, which is +$1 and got my return, so IRS would not flag it as an issue. The only lost is you will be getting $1 less on your return.
TurboTax should fix this issue.
