Mortgage interest calculation is not working correctly with TT Software. Where can I get help to address this issue?.

If the home was originally purchased in July 2017, the interest paid on up to $1 million of mortgage principal is fully deductible. Make sure your entries in TurboTax match these:

1. In the Federal > Deductions & Credits section of your return, scroll down to Your Home and click Revisit/Start next to Mortgage Interest and Refinancing (Form 1098)
2. Add another 1098 or edit an existing one.
3. Answer the questions and enter or verify the information as it appears on your 1098. Make sure you have both the box 1 amount and the property taxes if they are reported on the form.
4. Answer What kind of property is this loan secured by?
5. Answer We didn't pay any points .
6. Answer No for the loan you refinanced out of to Let's see if this is the most recent form for this loan.
7. Answer Yes to Is this the original loan used to buy your property? for the original loan

For the second 1098, you would do the same except answer Yes in step 6. For Step 7, you would say No to Is this the original loan then Yes to Is this loan a HELOC or a refinance? and answer to Did you take cash out?

Note that if you took cash out and did not use it to improve the home, that portion of mortgage interest is not deductible.

After you enter both mortgages, both should be flagged with Needs review. For the old mortgage, you want to enter the date you refinanced and the amount you owed on the loan when you refinanced. It then asks Do either of these apply to this loan? Answer Yes because your original loan was secured in 2017. 

For the new mortgage, you can leave the date of payoff blank and enter the balance as of January 1, 2022 which you should be able to get from your mortgage statements. Again, answer Yes to Do either of these apply to the loan? 

Once entered that way, if your mortgage is under $1 million then the entire loan interest should be deductible.
