I need to file a 990 for calendar year 2017 and calendar year 2018 using 2018 Proseries. How do I change the year to 2017?

You use the program Pro Series 2017, to work on 2017 tax year.

You use the program Pro Series 2018, to work on 2018 tax year.

Etc.

You need to install ProSeries 2017 and do that return first. Then transfer that processed file to 2018 ProSeries to do the 2nd year.
