State ID for form 1099R: Enter a PA distribution type. Can't figure out what to enter>

I am stuck in PA State filing. Last year I had no issues. But this year, I am stuck here.

Check your entry:

Gross compensation worksheet: State ID for Form 1099R: Enter a PA Distribution type.

I have only 1099-R for my RMDS. There seems to be no choice. 

What shall I do? I already paid TurboTax file it.
