Deductions & credits

@wflord It appears the "Mortgage Interest Deduction" worksheet is working now.  I put in a mock situation that may be similar to yours and the calculations appear to be correct.

Here is the mock situation and TurboTax entries: Begin by deleting all 1098's you have entered and "Done" to get back to the original state.

1st 1098  box 1 - 5,000  Box 2- 800,000  Box 3- 3/3/2021 Box 7- checked 

1. Follow on page about points checked "This is a new loan on which I paid points in 2021.
2. Loan start date 3/3/2021
3. Length of loan 30
4. Points paid 2000
5. Checked this loan was paid off
6. "No" this is not the most recent form 1098
7. "Yes" this is the original loan

First time mortgage sold 1098: 

Box 1- 1000  Box 2- 798,000  Box 3- 3/3/2021 (same as original loan)  Box 7 checked Box 11 8/8/2021 (date mortgage sold)

1. Select "I have no points to deduct"
2. "No" it is not the most recent 1098
3. "Yes" it is the original loan (not a refi just sold)

Second time mortgage sold 1098

Box 1 - 1000  Box 2- 797,000  Box 3- 3/3/2021 (same as original) Box 7 checked Box 11- 11/1/2021 (date mortgage sold)

1. Select "I have no points to deduct"
2. "Yes" this is the most recent 1098
3. "Yes" this is the original loan (not refi just sold)

"Done"

Put in purchase dates for all three loans (Should all be the 3/3/2021 for the original loan) 

Put in the pay off principal for original loan (Box 2 principal amount on 2nd 1098) and date loan acquired (Box 11 second 1098)

Put in the pay off principal for 1st time mortgage sold (Box 2 principal amount on last 1098) and date loan acquired (Box 11 last 1098)

Put in end of year balance for last/current mortgage holder

"Continue"

Got to Forms View to check Schedule A - you should see amounts on 8A and 8C (both limited due to post 12/17 $750,000 limit) and then the total on line 10.

You can also check the "Ded Hom Mort" worksheet and the "Home Int Wkst(s)" to see calculations.
