Amendment showing refund despite no changes made

Hello,

I started a 2024 tax amendment. The page first said the meter would be set to 0. However, once I start, without making any changes at all, it is showing a federal and state refund due with the amendment. I don't understand how this can happen without making any changes to the prior return.

Thanks.

It seems that the difference is driven by a change in the calculation of line 8a of Schedule A:

"Home mortgage interest and points reported to you on Form 1098."

This is odd because I haven't changed any details pertaining to the 1098 from the prior year (2024)

Why would this change? 

Thanks.
