I have different insurance than I posted on my tax return can we revise that

Which state?  

As long as you have coverage and reported that you do, it may not matter.  However, if you are in a state that it does matter, then you can Amend Your Return for the state to update the insurance information. 

Did you e-file already?  The only thing you were supposed to enter about health insurance on your federal return would be if you have a 1095A for marketplace health insurance.  aka "Obamacare" aka "Affordable Care Act" insurance from healthcare.gov.   If you have a 1095B or a 1095C you do not enter those at all.
