To address some of your questions:
- Yes, you need to purchase a specific year software in order to prepare that years tax return. So in your case, that would be 2019.
- I would recommend you follow the interview process. This is a safer bet that nothing is missed in the preparation process.
- When following the interview process, TT will provide assistance in the efiling.
- I am an advocate for "if it sounds too good to be true, it generally is". So for me, I would be willing to spend the $$ to purchase the product from a reliable source such as TT. This ensures you get what you pay for. Just to be clear, I am in no way affiliated with TT.
- The TT site for TT Business indicates that the state product is additional.
*A reminder that posts in a forum such as this do not constitute tax advice.
Also keep in mind the date of replies, as tax law changes.
