Refiling 2022's return

Afternoon all,

I realized earlier this year that I could claim my mortgage interest (a portion of) for my rental suite. So I opted to use refile on Turbotax, however at the end after I've made the necessary changes it's asking me to pay the taxes I owe again (albeit a few dollars less as I've added more deductions). 

I've already received my return/paid my taxes but this change should give me approx. $300 back on my return. 

Do I need to pay the taxes again, and get a bigger refund? Or how can I avoid this?

TLDR: Last year wife and I had a return - of around NET $3000. (I received 3300, she owed 300.) After adding the deduction (we split ownership of the rental 50/50) I am now receiving approximately 3200 and she only owes $190. 

However, I already paid the $300 dollars she owed last year when we originally filed our taxes. Now because I'm refiling, the software believes I owe $190.00, even though technically I'm ahead $110 because I paid $300 already.

Is there a way I'm supposed to be doing this that I've missed?

Thanks.
