ABP Interest Adjustment - Data source?

skil — Mon, 09 Mar 2026 08:14:16 GMT

On Schedule A, TT deducted $54 for ABP Adjustment. I understand this means amoritizable bond premium, but I really trying to figure out where the amount came from. I have a few 1099-INT forms, and only 2 have lines filled in other than standard interest (line 1) - both forms are from Fidelity. One 1099-INT has 27 cents on line 11 (bond premium) and the other 1099-INT has a few hundred on line 13 (Bond Premium on Tax-Exempt bond) generated from municipal bonds. Only the first 1099-INT is from an account that contains taxable bonds.

So, how do I know where this -54 is coming from on the Schedule A ?

"ABP Adjustment" would be reported on Schedule B.

The "1099-INT has a few hundred on line 13 (Bond Premium on Tax-Exempt bond" would be the source.

Amortization is required on tax-exempt bonds.

Thanks for the reply and link. I understand the concept, but the reply is not answering my question of WHY

I am manually typing my 1099-INT, no import. How can I find HOW or WHAT the software is doing to get the -$54.11? As far as I can tell, the amount is ONLY appearing on Schedule A. I just don't get how the software can figure this out from a single entry on line 11 of one 1099-INT and a single entry on line 13 of the other 1099-INT. For the latter 1099-INT, I did key in interest, state by state, for the tax exempt interest that made up line 8 of the 1099-INT. But, of course, the tax exempt bond premium was entered as a total only on line 13.

The only other thing I can think of is I have a 1099-OID with line 6 of $53.84 (acquisition premium). This amount doesn't match the -$54.11 TT is deducting on Schedule A.

I definitely see on Schedule B the -$54.11, so thank you - I can adjust it if I want. But, any idea of where the $54.11 is coming from ?

53.84 + .27 = 54.11

"One 1099-INT has 27 cents on line 11 (bond premium) "

"1099-OID with line 6 of $53.84"

Thanks ! Right under my nose - appreciate you helping me connect the dots. Hope this help others realize some of the ABP can come from 1099-OID.
