Following my previous comment, I found the tax forms I was working on, but they were titled by the Form, not saved documents. Taking me well over an hour due to the labeling. Need a Saved Documents Option to simplify it.

The only thing I really had a problem… The only thing I really had a problem with is that I completed what I thought was a "free" form and then had to sign up for a free trial. The actual program is very useful and helpful and relatively easy to navigate through.
