There's no substitute for just getting in there and preparing a return and getting a feel for the program.  

Its forms based, so you can enter things directly from the tax return line by line, double clicking a line will open a worksheet to enter what needs to go there, so if you are familiar with looking at tax returns, it really shouldn't be too steep of a learning curve.

The WHERE DO I ENTER button still saves me on almost a daily basis, finding what I'm looking for (since they changed the forms for 2018!), it saves time rather than scrolling through all the lines of the new forms they gave us.

This group is a great place to ask questions, much quicker than calling support!   There is ProSeries Facebook group as well for questions about using the program.
