I didn't mailed the file from 2015 yet and now I am looking to recover my taxes from last year but I also want a direct deposit on my bank account. How can I do this?

On January last year I filled the form for my taxes but unfortunately I missed the deadline because I wasn't sure if my bank account is still available or not. Now I want to recover my taxes from last year and I would like to use my actual account for this.
I used the app and I filled my account and routing # but I have no idea what to do next.
