Why are they sending you more refund?  For what year?  Did you mail in an Amended return?  

Watch out for scams.  You might get a fake deposit and then the scammer will ask for it back and then you find out the fake deposit bounced.

I messed up when I filed last year and forgot to add in the childcare so I put in an amend when I filed this year about it

Ok it should show up here.
