Well, the box 2a amount will be the taxable amount on line 4b of the form 1040. (plus the taxable amount of any other IRA 1099-R forms you entered)
And as long as the exact same box 4 value is in "Software's" box 4 entry for that 1099-R form, then you most certainly got Federal credit for having paid it. Of course, the 10% withheld may have been less than the eventual tax applied, based on your total income...so you may still owe the difference. Like, if your income is already in the 22% tax bracket, you'll owe another 12% on the 2a value......or even more if you are in a higher tax bracket.
Just make sure the box 1, 2a, and 4 values on your paper form are the same as what you see on the software's 1099-R form for that Payer.

Still don't trust it? then delete that 1099-R form entirely, and re-enter it entirely manually.
