.........in box 10 (not 😎 and 12 on the 1099-INT in the software.
If you look at the main page of the 1099-INT form...where you can see box 1 ?
Look for a CHECKBOX ! "My form has info in more than just box 1 (this is uncommon)"
Make sure you have a box 3 entry to go along with box 12....not sure about box 10.
And do not put a 0.00 in any box..any box with a zero in it should be left empty (maybe box 1 would be OK...last year the form wouldn't go without at least a 0.00, or real number in box 1, but they may have fixed that)

(.............though it's stupid to say it's uncommon...we just can't get the developers to eliminate that ridiculous statement)
BUT...for the box 10 entry, you also need to make the following manual change to your 1099-INT
"If you made an election to include market discount in income as it accrues and you notified your payer of the election, the amount on this line is the income that must be included in your taxable income.
To include that amount in income, adjust Box 1 and/or 3 (based on the type of bond the accrued interest is from) to include the amount reported on the Market Discount line. "
