Under Sale of your Principal Residence "Proceeds of disposition" it says Locked items require an upgrade on the next page. What does it mean and how do I get rid of it?

If you are using TurboTax Online, a lock means you'll need to upgrade the version that you are using if you need to use that item.

But the upgrade is for flipping properties and this was my primary residence I sold. So why would I have to upgrade I didn’t flip any houses?
