What state?  What error message are you getting?

Can’t file my Michigan state tax return keeps saying fix social security format but all is correct ??

I recommend the following steps to make sure everything is entered properly. 

1. From the left menu>My Info and double-check your social security numbers are correct
2. From the left menu>Wages & Income>Social Security (SSA-1099, RRB-1099) and click Edit/Add
3. From the left menu>State>Michigan click Edit>Income and click Edit 

The Social Security format may be affected if it was accidentally entered as Railroad Retirement Benefits, for example, when that does not apply. Running through the interview would verify everything was in order.

I filed my Federal return electronically but have to file my PA state return via mail.  I went to print the PA state return but received an error message (no description of the error).  However, when I checked the PA state return (via TurboTax program), I didn't get any errors.  How can I find this error?

I recommend running the state review again using Chrome.

If nothing is identified again, you can have confidence your Pennsylvania return is ready for submission. Are you filing any local taxes by mail, as well?

It is a best practice to send it via certified mail so you can prove when it was sent/received.
