I need to update my phone number but already filed!

You can still update your phone number. 

Login 

Go to Inuit Account in the bottom of the black column on the left

Edit your phone number

This will not update your phone number with the IRS, but the IRS will not call you regarding your taxes. If there is an issue, they will send you a letter. The same is true for your state tax agency.
