I input a bad number on the worksheet to calculate taxability of state tax refund. How can I get back to screen to correct?

Go to Federal Taxes

Wages and Income

I'll chose what I work on

then scroll down to

Other Common Income

the first one is State Refunds and Edit it and re-do it.

You keep asking questions, but give me some more detail so I can help.  
Did you try to do what is above?
