You asked a question that doesn't really apply to "using ProSeries to prepare client income tax returns." So, you are in the wrong place on the internet. You need to use other resources. Examples:

https://www.irs.gov/businesses/small-businesses-self-employed/self-employed-individuals-tax-center

Because you described your Profession. That isn't going to control anything having to do with your tax obligations.
