You should mail the full returns. Even though you only changed the one 1099-R it changed your total income on the 1040 as well as a bunch of other numbers that can flow off of that. It's a good idea to mail the whole thing.
When you print the returns TurboTax will have a page on the front that has the mailing address for each return. But just in case-
