I worked for 2 different companies in 2019 and overpaid social security tax. The overpayment of social security was reflected in schedule 3 part 2 line 11 however it was not reflected in line 18 D as a positive adjustment. I am trying to determine if the overpayment was included in my return or if I need to submit form 843 (claim refund/abatement). Thank you in advance.
