You will have to wait for your refund, then you can go back 
into your Turbo Tax account and do the amendment, print off the return, 
attach all papers they ask for and mail your amended return back to the 
IRS or State, Also if you need to track your return you can go to
 IRS.gov "Where's my refund" or if you are looking for your state 
return, you would go to which ever state you are in department of 
Revenue and "Where's my refund".  Since you mailed them in I would wait 
at least 2 weeks to allow them to get it and process it.
