So the USPS called me, on a Sunday evening (!?), and said that the package is being returned to me. They said it can take up to 2 weeks. It has been over 2 weeks but he assured me it hasn't been lost. The tracking status did change slightly. They added "Your package will arrive later than expected, but is still on its way." We'll see. I'm guessing returning a largish package due to an address error is not high on their Priority (Mail) list. I'll let you know if anything changes.
