Why is Turbo Tax not accepting the Payer’s zip code taken directly from my 1099-R? It says it is invalid.

I would try delete the last four digits of the zip and seeing if TurboTax is happier with this. Those digits are almost certainly unimportant in the grand scheme of things.

Where is TurboTax not accepting this? On a W-2? On a 1099-R? Someplace else?
