Normally the name control for a trust or estate are the first 4 letters of the trust/estate name. It looks like TurboTax is picking up the 1st four letters of Estate as the name control. If this is for an estate, try the first four letters of the deceased's first name. If that doesn't work, then try the last name. If you have the letter from the IRS that assigned the EIN number to the estate, review for the first four letters from that form. John Doe Estate name control would be JOHN.
