You cannot use TurboTax Online to file for 2017. TurboTax Online is only for the current tax year, which is now 2019. To file for 2017 you have to use the CD or download TurboTax software for 2017. You can purchase a download at the following link.
You might get a better price from a reputable online seller that still has TurboTax for 2017 in stock.
You can use TurboTax Deluxe, Premier, or Home & Business, but Home & Business will give you the most help and guidance for filing as an independent contractor.
Tax returns for past years cannot be e-filed. You will have to print your 2017 tax return, sign it, and file it by mail. The IRS stopped processing mailed tax returns for several months because of the Covid-19 pandemic. They just recently started to process them again, but they have limited staff and a huge backlog, so it will be quite a while before your 2017 tax return is processed.
