Retirement tax questions

2022 was one of the 8606 I did not submit.  I put in 7000 on 2023 tax year 8606 form because a know I contributed 7000 for the 2022 tax year based on the 5498 I had.  This whole mistake was because of my lack of understanding the 8606 form.  I thought the basis was just the previous year's contribution.  I will put that in the explanation with the 1040-X and corrected 8606.  Thanks!
