Alan, a POA ceases to remain valid at time of death. Everything transitions to the estate and requireds a "court" appointed representative. Contact your court probate office for details. Not my first rodeo - completed my in-laws' returns, dad, sister (who was intestate) and now mom's. I didn't wait for TurboTax to get their act together and simply mailed it in with a 1310 off the IRS website. But now TT is updated so have at it. BUT, you still have to mail in your appointment. Regardless of your next of kin status, you can not get around the legal requirements for a duly appointed estate representative.
