note if you have multiple types of income on the same 1099-INT - Box 1,3,8 then you need to input the box which has the accrued paid as a separate 1099. Turbotax doesn't know how to allocate adjustments and will apply it across all the boxes unless you split it up.
also if the next interest coupon after a 2025 purchase falls in 2026 then the accrued would be applied to your 2026 taxes to line up with the income, in this case you have to track and carry it over. depending your brokerage they may just give you a report of accrued you paid in 2025 but no guidance whether they applied to a 2025 coupon or not.
