TurboTax told me that I need to do so: https://ttlc.intuit.com/turbotax-support/en-us/help-article/amend-tax-return/amend-2020-return-mortg...
However my mortgage is less than $750k.
I think that TurboTax interpreted my refi as having two loans of that amount for the same home and believed I was above the cap, which I'm actually not.
