Do I a certified preparer to sign the last part of the injured spouse form if I am filing it separate from my return and I file my tax myself online?

I am filing it separately, my return was already accepted and part 4 says I need a certified preparer to sign, do I need one when I did mines myself

No, you would sign the line directly above the "Paid Preparer" section that says "injured spouses signature and date."  But, you do not fill out Part IV Paid Preparer Information since you are preparing it yourself.
