I am reluctant to file my 1040 because it is not yet known if 2018 PMI can be deducted or not. I haven't found the answer yet on Turbo Tax but I imagine there will be an additional fee to file the amendment, so I guess I'll just wait until Congress etc. actually does something to file my 1040 so I don't have to amend it later. Assuming Congress does something before the filing deadline. :(
