You're asking for Payer's street address but give no name for payer. I have several 1099R. What is the name of the payer?

It's on the 1099-R. Each one.

I can't give an address if I don't know which payer you need the address for.

This is a user community forum.  No one can see what you are doing.   If you are getting an error in the Review, and if there are no clues as to "which" 1099-R it is for, then you'll need to go back to the 1099-R interview and see if you have the address shown for each one.

If it's a standard IRS 1099-R form and not a customized form, the Payer's name and address is in the top left corner.

Here's an image of a standard 1099-R.
