Not sure what you mean by "no taxes on a 1099-R", but the following steps should stop the program from asking about the Schedule K-1.
Use the "Delete a Form" tool to remove the Schedule K-1 (and any associated worksheets).
See: How do I delete forms in TurboTax Online?
After deleting the Schedule K-1 (and any associated worksheets), log out of the program. When you log back in, use the Delete a Form tool (List of Forms in My Return) to confirm they have been removed from your return.
Why does this happen? When you transfer the information from your prior year return, the program automatically includes certain forms in the current year - to make sure you don't forget to update those forms. If a form is no longer required (e.g. K-1s, Schedule C), you have to delete them from the current year.
