I have a 1040-X filled out due to the fact that I received a 1099-INT after I e-filed my taxes with Credit Karma and I did not list a qualified HSA distribution on my 8889. The official instructions for filling out the 1040-X are not available on the IRS website yet. The most recent revision is for January 2019, but the 1040-X form is up-to-date as of January 2020. Am I able to mail my 1040-X in or should I wait until the instructions are officially up-to-date?
