I would not do anything until you receive your refund. You have up to three years after the original due date to file an amended return, so plenty of time.
I'm not sure what your original filing contained, but you are able to amend Form 1098 within TurboTax:
- Sign in to TurboTax
- On your Tax Home, scroll down to Your tax returns & documents, select 2021, then Amend (change) your return
- Select Amend using TurboTax Online
- On the screen OK, let's get a kickstart on your 2021 amended return, select Changing other info on my return and Continue
- Answer the questions on the following screens. The Refund Monitor will reset to $0—don’t worry, this is normal for amended tax returns
- When you reach Here's the info for your amended federal return, select Start next to Mortgage Interest and Refinancing (Form 1098)
- You can enter your calculated amount for the Outstanding mortgage principal reported in Box 2. Your federal (and possibly state) refund should adjust if the change in principal impacts your taxes
- Continue through the screens, making the changes you need to make to amend your return
