Thanks for all the good information about the stimulus payments, everybody!  Based on what you gave me, it appears that both of ours should have come through electronically on the 9th, so...hmph.  

Could be an issue with the bank account, because I had to freeze it when my purse was stolen, but I had it set it to receive deposits only in anticipation of this coming through (so anyone who wants to deposit money into my old checking account, feel free to do so any time the urge strikes).  I'll give it a few more days and see what happens before doing anything that resembles actual work to find out what's going on.
