I know it’s horrible but I haven’t filed my taxes in three years since 2017 so what do I do now? I called H&R Block and they were completely rude and unprofessional so I rather take my business elsewhere. I’ve used turbo tax in the past. I’m just not sure if I should be using turbo tax with three years of taxes I haven’t done. Or should I go to another tax professional or try turbo tax again?
To do your taxes using TurboTax, the current online product can only be used for 2019 tax return. You would have to buy and download to your computer the CD/download products for each of the previous years. You should start with the oldest year first so that you can transfer information from one year to the next when preparing each subsequent year's return. Prior year returns can only be printed, signed, and mailed. They can't be efiled. You should mail the return for each year in a separate envelope and mail it such that it can be tracked.
Here is where to buy the prior years: https://turbotax.intuit.com/personal-taxes/past-years-products/
There is no way to know whether you should try to do it yourself or go to a tax professional. The program is fairly straight forward for most people with simple tax returns.
Do a web search with something like Google; search for "IRS Publication 501". Or, you could let somebody do that for you. Here, here's one link: https://www.irs.gov/forms-pubs/about-publication-501
I agree with the first answer to your question. You will need to obtain, perhaps for a fee, basic TurboTax on CD or by downloading. Do oldest year first; TurboTax will bring forward several things into subsequent years to speed things along.
Now, if Pub. 501 exempts you from filing, good for you.
Nevertheless, perhaps you're wanting to eFile in order to facilitate processing for CoVid-19 credits, in which case you could eFile TurboTax for 2019 (the sooner the better, for that purpose). 2019 filing software may be free if you use an online version or such.
One may file currently due simple returns directly with IRS: https://www.irs.gov/filing/free-file-do-your-federal-taxes-for-free
Because you do not have a high income, it's possible that your taxes may be so simple that you could file prior late years on a 1040-EZ paper form. Such forms are downloadable: https://www.irs.gov/forms-pubs/about-form-1040-ez
Depending on what Pub 501 says about whether you need to file or not, you must file if you were paid in cash or on a 1099-MISC in order to pay self employment taxes. If your W-2 income is low enough that you don't need to file a tax return, you should file anyway to get a refund if any federal income tax was withheld. You would have to weigh the cost of the software vs. the amount of refund if you don't use the IRS forms and do it by hand.
See IRS Pub 501 Table 3 "Other situations"
There are seven circumstances listed.
"3. You had net earnings from self-employment of at least $400. (See Schedule SE (Form 1040 or 1040-SR) and its instructions.)"
