Tax Return Amending

I had originally filed my health insurance coverage to be from October 2016 to December 2016. I just received my 1095-B in the mail and it tells me I actually had coverage from August 2016 to December 2016. When I tried to amend this on TurboTax, the system tells me it detected no differences between my original and my amended return. Should I still continue with amending it or leave my return as is?
