Thanks JAMESG1for the suggestion.
I originally imported the 1099B, 1099-DIV, 1099-INT, 1099-MISC and 1099-R directly from my financial institution. I deleted only the 1099-MISC information along with any supporting schedules related to it. Then I manually entered the 1099-MISC information and ran the TurboTax Smart Check again. I'm still getting the same one error relating to Select an existing Schedule C to link.
I think I encountered a similar error when working on my 2020 taxes. But, I think was still able to successfully transmit my 2020 return with the one error as it didn't impact the income or taxes any. The field looks to be informational only.
Seems TurboTax won't let me proceed to file electronically this year until this one field is corrected.
