Does this system pre-populate the forms with everything the IRS already knows about me and then I just modify the things that are incorrect? Can people upload their tax documents from all the financial institutions in some standard format that automatically figures out what form to use and populates maybe 95% of the fields and marks the empty required fields with yellow? I ask because I have an id.me/IRS login and they do not appear to have this data until I give it to them.

This is the system I am looking for. I think it would make the lives of the IRS employees better and would save me time and money.
