How long to process I-800A????

We mailed our application about 2 weeks ago. Then got the receipts, but the information (name and address) are wrong. So talked to our agency. They provided us the local USCIS's email. So emailed them with corrected information. And at the same time, they email us the notice for the finger print. FP was taken on Fri. On the receipt of I800A, it said it will take about 60 days. We also received another 2 receipts (husband and wife) for the FP, it said it will take up to a year. So I don't know which one is correct.
