Deductions & credits

@PMAK @JantovenNF I'm not sure it's a TurboTax issue - although I wouldn't let them off the hook as this is clearly a complication for their users, so they should at least address it.

Below are some screenshots from the forms view after I entered all of my information through the wizard. I've circled in red the important values. As you can see, based on the worksheet calculations, it is combining my original loan ($452k) and my refinanced loan ($451k) to come up with the limited deduction total ($902k). What I ended up doing was zeroing out the "Outstanding mortgage principal as of 12/31/2020" (Value E on Home Mortgage Interest Limitation Smart Worksheet") because, in fact, the outstanding mortgage principal as of 12/31/2020 on that loan was $0.00. This brought my limited deduction total into the $600k range.
