Intuit Turbo Tax is very confusing about e-filing state tax.
I completed the Return and elected to mail it in. Later, I decided to e-file. I went through the filing process until I got to the point where I purchased the State e-file option. Once I received the confirmation of my purchase, I assumed my previous selection to e-file would "grab" the State Return and file it. No such luck.
After several days of not receiving notice that my return was accepted/rejected, I logged back into my file and saw the State Return had not been filed.
You can do beter.
