If you have other quality evidence, I wouldn't wait more than a couple weeks. The 2023 tax return can be uploaded later or presented at an interview (if you are so "lucky"). As the others have said, wait a day or two into the 90 day window to submit the I-751 package. Good luck. It gets much, much easier after Removal of Conditions. Keep your eye on the target----getting out of the grasp of USCIS!!
