Please follow the steps below to report the adjustments:
Form 1099-int worksheet box 1 will show the interest amount and if you scroll down to Adjustment to Interest you'll see the adjustment amount.
Form 1040 line 2b will show the taxable interest after the adjustment.
Schedule B is only necessary when you receive more than $1,500 of taxable interest or dividends.
This is for Charles Schwab. I entered the accrued interest per your instructions. On the Form 1099-INT worksheet for Schwab, the Adjustment to Interest section is blank. No box checked, no amount entered. The amount on Schedule B line 1 for Schwab is the same amount as what's on the 1099-INT without adjustment for accrued interest.
