If you are seeing a Form W-2 that you no longer need, delete it. See: How do I delete forms in TurboTax Online?
@Click is correct - "If you imported data from Turbotax 2019, then you should expect to see W-2s, 1099s, etc. for the same payers as last year."
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 or report income that you had in the past and might still have. If a form is no longer required (e.g. W-2, 1099-R, K-1s, Schedule C), you have to delete them from the current year.
