I filed my federal taxes. It took the code I got from a vendor. Now I go back to file my state taxes and print my forms. The system takes me to continue &pay full amount.

I would advise going back into your Federal tax return through the vendor link you used, and then click on State Taxes to prepare your state.

 

I don't know if the link you used includes the Efile fee of $25 for your State Return; that might not be included.  You'd need to see what your link says about that.

 

Here's more info on Filing Federal and State Returns Separately.
