After you file

Thank you for your advise.

I thought I have to wait till 1040x is processed before I file/mail state return.

(I thought if any correction is made by IRS on my 1040x and then I have to use the correct number on state amendment just to be sure... I don't think there is any error in my 1040x though...)

 

What is the usual practice in terms of state amendment filing after 1040x is filed?

 

I just checked my usps tracking and my 1040x was delivered just yesterday.
