Get your taxes done using TurboTax

How much weeks it can take?  Unknown ... this is an internal situation and there is no way to "check" on it.   If you used the ITIN on the 2019 return then the 2020 return may have to be mailed in but other than that the change will be behind the scenes. 

 

Also will IRS notify us after changes done?  No they will not.
