Almost perfect. For the new loan, when it asks When did you buy the home with the loan from the second lender? Enter the date that you originally purchased the home, not the date of the refinance. If you originally purchased the home before December 15, 2017, then your entire mortgage interest should be deductible.
Once you change that answer, if you have an older loan, TurboTax should tell you all the interest is deductible. If it is newer than that, a small portion of your loan may not be deductible. If you are getting deductible interest around half the interest you paid, TurboTax may be calculating wrong based on your entries. In that case, delete the forms and re-enter them using the same answers you gave.
