Made mistakes on Federal and PA state 2025 income taxes.

I did my federal and PA state income taxes for 2024.  I electronically filed both.   I got a message back the these returned were accepted.  However, the refunds were very high (Fed - $7,183.00, PA State - $12,191.00).  This is my first time filing after a full year of retirement. It appears that I did not input my income correctly.  The income included my wife’s Social Security, payment from her retirement and a small income from a job. It also included my Social Security, my pension and my retirement.  I have been told that I need to file a 1040X and a new PA State return.  I am reluctant to file either without some assistance because I am not clear as to what income is taxable and what income is not taxable on either return.

I filed my Fed and State returns on time. I am starting here for assistance but I am considering meeting face to face with a tax professional

What is your recommendation for pursing this problem?  I have not heard anything back from the IRS or from the State of Pennsylvania.
