@wendyle1993 , if you are using a TurboTax Windows CD / Download version then the following should work ( I say should because I do not have access to PA software but both CA and MI generally work this way :(
While you are the State program , select "forms" from the top right hand ribbon; this would result in TurboTax showing two panes -- left shows the forms and worksheets and the right pane shows the form/worksheet selected on the left pane. Select the worksheet that shows income i.e the worksheet for PA-40. on the left pane.
Now you go into the form and correct the entry (you may have to right click on the entry and choose "over-ride", enter the correction , enter and go back to form PA-40.
Once all changes are done , go back to step-by-step mode ( top right hand ribbon.
Now move forward on TurboTax so that it runs the check.
Hopefully this will work for you
