My e-file is still in progress but can I make this correction now?

If it is in progress you haven't filed yet, so yes, you can make a change.

You cannot change or add anything on the return that you just e-filed.  It is too late, just like when you put an envelope in a US mailbox

Now you have to wait until the IRS either rejects or accepts your return.  If your return is rejected, you will be able to go into your account and make the necessary changes to your tax return and re-submit your return.

 If the IRS accepts your return, however, then you have to wait longer until it has been fully processed and you have received your refund.  THEN you can prepare an amended tax return and mail it in. You will need to use a form called a 1040X. You cannot e-file an amended return.  They have to be mailed, and it takes at least 2-3 months for the IRS to process an amended return.  Meanwhile, DO NOT go in and start changing anything on your return in the system, or you will make a mess for yourself.  Sit tight and wait until you see what the IRS does with the return you just e-filed

Ok Thanks. I will wait.

"In Progress" means that you have started your return, but have not yet completed it.  If that is indeed where you are in the system then you can fix what you need to fix and then submit the return for filing.

I used Sprintax software last year to file 1040NR-EZ?

Then it is possible that you itemized. You may need to amend your 2016 tax return. I have included amended instructions above.

thanks a lot

If it is progress, does that mean you have not efiled yet?

no it is e-filed!
