Deductions & credits

I don't know if I can continue with this thread or not, but here goes. 

 

I'm really getting worried.  My return was accepted on Feb. 15 and TT estimated a 3/5 return date.  I still haven't received word.  I went into the IRS' "Where's my refund" and it says it's still being processed.  I want to amend  my return, correcting the mistake and resubmit it, but I guess I can't do that yet.  Is there anything I can do other than continue losing sleep?   Thanks for any suggestions you might have.
