Thanks Chatter. I've definitely struggled a bit with the communications these last few days, and I appreciate the pointers to help move me in the right direction.
I actually got an email from W about an hour ago, saying that her tax return was rejected due to either an improper PIN for e-filing or an improper AGI.
I'll respond "AGI I sent last night was directly off your 2010 filed return. I will scan and send to you tonight for your records."
