Never recieved 2017 refund

when did you file 2017? if it was after 4/15/2021 you filed too late. your refund is forfeit.

When and how did you file a 2017 return?   Did you file it on time sometime in 2018?   Or did you file it late and mail it in?   As explained.....if you waited to send it in after April 15, 2021, you will not receive the refund because it was too late.
