Filing multiple years of returns

[JudyB]

Should I file all together, or separate, and I am starting  with the oldest in case there is any carryover. 

Anyone have a good recommendation of getting these across to the IRS in a simple manner.

Most questions like this start out with details on how far back, and most of those are going back way too far.

You should file each return separate. You can efile the current year, and the last two.
