I sent in my taxes online on the 29th of January and put it in as mail when i receive it. It's been around 4 weeks and i haven't gotten anything. I don't know what to do.

I did them on January 29th, app says it's done and "ready to mail" and everything. I did taxes online through turbotax app. I must have selected mail by mistake so it will take longer for me to receive my refund. It's now March and i still haven't heard or received anything. I can't check the status because it keeps saying information is incorrect, but it's really not incorrect whatsoever. Please can anyway help me out on what's going on?
