@IntuitJim  Does it allow you to enter wages from a second job?  If it doesn't, it isn't correctly reflecting the amount of FICA that is being refunded on the 1040.

Does the Schedule C to S-corporation show the details about how it affect Social Security benefits?  In my opinion any tax preparer (or software program) that suggests changing from a Schedule C to a S-corporation and doesn't discuss that is setting themselves up for a lawsuit when the unsuspecting taxpayer realized his Social Security (retirement, disability, spousal benefits, etc.) are reduced.
