it doesn't seem like any of the exceptions listed below to using the worksheet would apply to you but just in case
Exception. Do not use the Social Security Benefits Worksheet in these instructions if any of the following applies.
• You made contributions to a traditional IRA for 2022 and you or your spouse were covered by a retirement
plan at work or through self-employment. Instead, use the worksheets in Pub. 590-A to see if any of your social security benefits are taxable and to figure your IRA deduction.
• You repaid any benefits in 2022 and your total repayments (box 4) were more than your total benefits for 2022 (box 3). None of your benefits are taxable for 2022. Also, if your total repayments in 2022 exceed your total benefits received in 2022 by more than $3,000, you may be able to take an itemized deduction or a credit for part of the excess repayments if they were for benefits you included in income in an earlier year.
For more details, see Pub. 915.
• You file Form 2555, 4563, or 8815, or you exclude employer-provided adoption benefits or income from sources within Puerto Rico. Instead, use the worksheet in Pub. 915.
