Market Place insurance

I inquired about market insurance online and was signed up without my knowledge. I was told to start my policy that I would need to add a credit card to my account. The policy started, I never received my insurance cards or policy in the mail. Several months into 2024 I tried to pick up some medicine and my Medicaid was rejecting the prescription because of overlapping insurance. I called marketplace and cancelled the policy. I never used it but am being told I need to include a form for my taxes this year. Is this going to affect my return?
