i need to amend my state taxes for this year

You cannot change or add anything on the return that you just e-filed, nor can you stop it.  It is too late, just like when you put an envelope in a US mailbox on the corner.  The IRS does not allow you to take it back.

If you left out a W-2, a 1099G, or a dependent, or a 1099 etc…DO NOT change your return while it is “pending.”  The changes will go nowhere.

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 e-file or mail  it in. You have to be able to work from that return exactly the way it was when it was e-filed originally.  You will need to use a form called a 1040X.

  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

The Form 1040X you need becomes available in late February,  But wait until your return has been processed.

The state tax return information flows from the federal return, so the advice provided by xmasbaby0 for amending the federal return applies to the state return as well. 

You will need to wait until the state accepts or rejects your tax return before amending. If accepted, you will need to wait until you receive your refund or pay the balance due before amending the state tax return. If rejected, you can make the necessary changes to the state return and re-file it. 

If you are amending your state return, make sure that there are no changes to the federal return that require an amendment.
