Sounds like just one of your W2s is wrong. Check boxes 3 & 4. How much is in each box? Box 4 should be Box 3 x .062 up to a max of 8,853.60. If box 4 is more than that you need to get a corrected W2 from your employer. Try leaving the cents off box 4. But also go back and double check your W2 entries, you may have entered box 3 & 4 wrong. A lot of people who have asked this found they did enter an amount wrong.
Or check W2 box 12. You may have entered Code A by mistake.
For 2021 the max for Social Security is $8,853.60 on $142,800 of wages (142,800 x 6.2%).
You only get excess SS back if one person had more than 1 employer and those employers took out more than the max of $8,853.60 (for 2021). If one employer took out more than the max you have to get it back from the employer.
Check 1040 Schedule 3 line 11 which goes to 1040 line 31.
