From instructions posted on the IRS website as of 4/2/2021. (As mentioned earlier, the Social Security Benefits Worksheet instructions are not correct, should say Schedule 1, line 7, not line 9.)
"When figuring any of the following deductions or exclusions, include the full amount of your unemployment benefits reported on Schedule 1, line 7 (unreduced by any exclusion amount): taxable social security benefits, IRA deduction, student loan interest deduction, nontaxable amount of Olympic or Paralympic medals and USOC prize money, the exclusion of interest from Series EE and I U.S. Savings Bonds issued after 1989, the exclusion of employer-provided adoption benefits, the tuition and fees deduction, and the deduction of up to $25,000 for active participation in a passive rental real estate activity. See the specific form or instructions for more information. If you file Form 1040-NR, you aren’t eligible for all of these deductions. See the Instructions for Form 1040-NR for details."
