The timeline I just went through for the exact same thing.
Received letter on Feb. 25th, faxed in my 8962 and 1095a same day (8pm)
On March 5th, Topic 152 was added to my check my refund profile (amount disappeared)
Today, March 7th, Bar returned with Refund Approved and expected refund issue date on March 11th
Doesn't take as along as they say it does. If you wait a week and then call them, they should be able to confirm the receipt of the fax according to status of your return. Hope this helped.
