Answering my own question...though I couldn't find my PDF of the 2016 filing, I had the print of it ,and found that I had included the correct amount for the 2016 IRA contrib. ON the 2016 1040 form!
The appearance of the paperwork from the bank AFTER we filed was confusing,and I hadn't thought to reread the print of the "AS Filed" till just now (panicked because I couldn't find the pdf -but relieved that I had the hard copy ).
Thanks for the quick response ,I have infact applied this latest (2017) contribution appropriately to this new 2017 1040.
