Further to previous. If the State forms are not available, it will cause this problem, and few of the help people seem to know it. So check whether the forms are available per my previous reply, and then wait a few day to try. I found that it takes at least one day. Also, even when it lets you purchase and fill it out, it sometimes may not be filed right away. TTax doesn't have dates for electronic filing, but the state tax ageency may.
This is one instance where procrastination is actually best. This has been happening to me for years on NY Business returns.
