Your assumption is 100% accurate this was in no way applied towards 2018 and it was after April.
This was and excess contribution made in error. My investment account and IRA accounts are under the same “parent account” I made the mistake of selecting the wrong account number when making the deposit. I am under 70 years of age and I do not believe that I exceeded my overall contribution limit with this deposit. I just had intended for the funds to go to the investment account and so I made the transfer as soon as I realized the $6000 inadvertently went to the IRA Account.
Box 7 is a #1 and IRA/SEP/SIMPLE IS Checked.
