This is an addendum to what has already been posted in this thread.
Unless the law changes, your 2020 tax return is due Apr 15, 2021.
1- Since this will be your first year dealing with business income/expenses, and if you want to tackle this yourself, do not wait until the last minute. Otherwise, it's perfectly possible (and highly likely) that the fines, penalties, backtaxes and interest could bankrupt all of your businesses before they even get off the ground.
2. While the download/CD version of TurboTax 2020 is available now, the program is not complete, and it is very doubtful it will be complete before Jan 31st, 2021. So filing early has a very high probability of coming back to bite you. It is my recommendation that you do not e-file until "AFTER" March 15th and "BEFORE" April 1st, 2021. This will allow time for critical updates to the program, as well as tax law changes to be incorporated into the program. If you e-file early and then learn later you need to change something in your already e-filed tax return, it could be a real PITA to deal with and you will regret having filed early. Amended tax returns can take weeks or months to process.
3. Being that you're dealing with three businesses for your very first time all in the same tax year, I would recommend you pay a CPA for at least that first year, to complete your taxes. This is especially true if your state also taxes personal income. Just make sure the CPA is clear that you want a printout of "EVERYTHING" that includes all calculation forms and worksheets - and not just your forms required for filing. You will need these printouts if you decide to tackle this yourself, in your second year. (weather you use TurboTax or not.)
