Q1: I did mean "add it to the form" which is to enter it into the form.
Q2: When you refinance the origination date becomes the date of the refinance. So enter 4/2/2020
While it is not wrong to have two entries, TurboTax sometimes combines the outstanding principle and then can make the amount incorrectly not eligible for full tax credits. That is why I advised to combine the two forms for one entry.
