If you call the IRS again you will get a different answer.
And if you call the IRS a third time, you will get a third different answer.
I’ve experienced this.
Keep going until you find one who has an answer you like and who closes the open case.
I would document the name of the IRS agent and his or her ID. Then I would document the time, date, and write down exactly what they tell you.
When or if you get audited, you will have proof of what you were told.
