This is a public user forum and it is not safe to post any personal info even your name. Sorry if you used the CD the only copy of your return is/was on your computer. Did you make any backups or print out a copy after you filed? You can not get the AGI from your W2. Only from line 7 of your 2018 1040 return. If you can't find it you will have to print and mail your return.
