What is on Schedule 3 that is wrong? Is it line 11 for excess social security tax? Sometimes that gets filled out wrong. Are you married or have more than 1 W2?
If you had more than one employer and the total of box 4 (only box 4 not box 6) on all your 2019 W2s for Social Security is more than $8,239.80 you get the excess back on your tax return. And it is for each spouse separately, not combined.
If you filed a joint return and both spouses have W2s you have to enter each W2 under the right name or it will look like all the W2s belong to only 1 person and too much social security tax was paid for that 1 person. And by assigning both W2s to the same person the program wouldn't know a W2 is missing from the spouse. It just would think they are both for you.
