After you file

What 'new debit feature'?

 

The original e-file was with direct debit.

 

The amended return asked how I wanted the refund, and I chose 'direct credit'.

 

So I don't know what you are saying. I never saw a screen where TT asked about the new balance due (all it ever showed was the refund based on the correction), and wasn't too concerned because the first had direct debit.

 

Maybe this is why the first advice I got was to wait on the amended return until after the original one was processed and the funds withdrawn from my account?
