I don't believe that I ever received my tax return for 2017. How do I find this out?? How do I get the money?

2017?   It is too late to get a refund for a 2017 return.   If you did not file a 2017 tax return, you forfeited that refund -- the last year you could have filed for a 2017 refund was in 2021.   You have three years from the filing deadline   (April 2018 or October 2018 if you requested an extension) to file a tax return and still receive a refund; after that, the refund is forfeited.   The filing deadline to receive a refund  for a 2017 return would have been in 2021. You can check your online account with the IRS to see what it shows for you.

Go to this IRS website for a tax transcript.  If your tax return was received and processed by the IRS there will be a tax transcript - https://www.irs.gov/individuals/get-transcript

If the 2017 tax transcript is available then go to the IRS website for your tax account to see if the tax refund was issued and sent - https://www.irs.gov/payments/your-online-account

If the refund was issued and sent but you never received the refund then go to this IRS website to request a trace for the refund - https://www.irs.gov/faqs/irs-procedures/refund-inquiries/refund-inquiries-0

If the IRS never received the 2017 tax return then it is to late to file a 2017 return with a tax refund.  The 2017 return with a tax refund had to be filed on or before April 15, 2021.
