Didn't the steps above work for you?  Go though the File tab and change it there.

Then only the IRS can tell you.  IRS Where's my refund https://www.irs.gov/refunds/

Make sure you are using the refund amount from your actual federal tax return and not the combined amount Turbo Tax showed you at the end.  That was for federal and state combined.

When you log into your account you should also see the status and if it was Accepted or Rejected, Started, Printed, Ready to Mail, etc.  what does it say?

I needed to fix my routing number

If you have not filed yet you can change your method and request the card. This Turbo Tax FAQ will show you how to change your method. How do I change my refund method? https://ttlc.intuit.com/replies/4288359

So about how long before you receive the paper check in the mail if the routing number was entered incorrectly. 

It can take 4-6 weeks to receive your check via mail. This is after the IRS accepts and approves your return. If your original check was returned to the IRS for some reason, it will take longer for the second check to be issued because they have to ensure the first check was not cashed.

Ii didn't put my full routing number  and it was accepted and got a letter saying I had the wrong information  then received a letter saying I get 0 I'm owed 1400 stimulus chck

I suggest you look at your IRS "Your Online Account" to see what the IRS has on record as having sent you for stimulus payments.

From there you can ask for a trace to see where the payment went.
