If you electronically filed a complete and accurate tax return you should receive your refund in about 21 days from the received date. If you mailed your return please allow 6 weeks.
Mine was also accepted on the 14th- under my husbands SS# awe get the same message you are seeing. Under mine we see its been received and the first bar, but not approved. Turbo Tax shows an anticipated deposit date of 2/4 but I don't see that happening if the IRS hasn't even approved it yet.
My understanding is the IRS ran a batch of early returns through the system to test it and that's why some were accepted earlier than the 28th start date.
