it keeps asking for info about a farm we sold 2 years ago

[ToddL99]

You need to delete those tax forms that reported farm income and expense from two years ago (e.g. Schedule F and associated worksheets).

See: How do I delete forms in TurboTax Online? 

After deleting Schedule F and 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 these worksheets and statements 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 F), you have to delete them from the current year.
