In January I filed 8606 forms for past years in which non deductible IRA contributions had been made. Will the IRS acknowledge these filings?

I want to file my 8606 for 2016 with my 1040. This 8606 would contain the updated non deductible figure based on the contributions for the past years I filed this past  January. Will the IRS acknowledge the 8606's for those years.  

Should I file my 2016 8606 which will reflect the first ever  RMD I took in 2016

It's quite possible that will get no acknowledgement from the IRS for the late Forms 8606 that you filed.

Prepare your 2016 tax return based on the assumption that the IRS has received and processed your late forms.  Your 2016 tax return is required to include Form 8606 to calculate the taxable portion of your distribution.  For the amount of your nondeductible contributions carried into 2016 from years prior to 2016, enter the total nondeductible contributions shown on the most recent year's From 8606 that you filed in January (usually line 14 of that form).
