Retirement tax questions

My situation is that I realize I did not always fill out the 8606s correctly. Every year I would make a non-deduct contribution and roll it over to a Roth.  No return showed a taxable distribution but often was not filled out correctly(showed no tax for the wrong reason).  Now I just have Roth IRA money and nothing in any regular IRAs.  Is there any reason to file corrected 8606s if it makes no difference?  I have the 1099s/5498s and the returns did not take any deductions.
