Can I do my small business taxes?

[VolvoGirl]

Need more info.  What kind of small business?  Is it a LLC or partnership,  etc. or do you just need to file schedule C for self employment, sole proprietor, freelance?

Or could you be asking about doing the quarterly estimates for 2023?

Most "small businesses" are self employment.  Self employment is reported on Schedule C.  Schedule C is an additional form (attachment) to your regular form 1040  personal income tax filing.  You do not file your self employment income separately. 

Using TurboTax online, you will have to upgrade to the self employment edition.
