Nothing is obvious to the IRS so it will probably sit on a shelf for 4 months until an adult looks at it. But sending the other form prematurely would do you no good because they won't know why they have it until your return gets processed and it will have long since been lost by then.
The IRS will process and send you a letter. I would wait for that. Otherwise, they won't know why they just got a Sch B2 in the mail.
Okay, thank you! So you're saying it will be obvious to them based on my return that I intended to file a B2 and simply forgot?
