After you file

I have an issue where upon preparing amendments to the Federal return (all I needed to do was to add non-deductible IRA basis to trigger form 8606) TT on-line goes through final federal validations, ask to confirm presidential fund, and uncommon situations and then... goes to Let's start your State return screen. I have only filed Federal and deleted auto-generated State shell earlier (because I file state manually). So I only need to amend Federal. How do I get the on-line version out of the loop of kicking off State in the process of Federal amendment? Or what am I missing as far as the process to submit federal amendment (alas, the on-line FAQ doesn't say anything about how it is submitted). Thank you.
