I netfiled my 2018 return, received a confirmation email as well as my notice of assessment. I need to make a change but Turbotax thinks I have not filed. What can I do?

We apologize for the inconvenience.  You are able to file an adjustment request.  Please see the following FAQ for instructions on how to submit an adjustment request.

Thanks but this answer didn't help. I could not find Return Manager. (How can I refile when TurboTax thinks I never filed??) We submitted the change thru MyAccount. I would still like my TurboTax to know that we have filed though! Autofill won't work next year!
