IRS Form 8606 Year-to-Year Requirements

In 2011, I made a non-deductible contribution for my traditional IRA.  During that year, I completed my tax forms correctly and submitted the required IRS Form 8606.  In subsequent years, I had not submitted any other 8606 forms listing the original non-deductible amount.  I must have overlooked this when filling out TurboTax each year.  Now I have realized that I likely should have been tracking this each year.  I am not retired, and have not withdrawn money from my traditional IRA over this time period.

 

Since I did submit my original 8606 form in 2011, the IRS would have a record of my original non-deductible contribution.  So my question is, should I simply properly submit my 8606 form beginning this year, or would I need to send the IRS forms for all of the years in between as well?  Would doing so trigger questions/audits from the IRS?  What is the proper path forward?
