There are no additional extensions. An extension for 2024 gave you until midnight on October 15 to file a return. If you are getting a refund there is no penalty for missing that deadline. If you owe tax due, you are subject to late filing penalties and interest owed on the tax due, which will be calculated only by the IRS--not by TurboTax. You do not mention what kind of inheritance you received; we cannot determine if it is taxable without more information.
Phone support is not provided with the Free Edition. If you are using a paid version of the software or if you purchased PLUS you can get phone support when customer support is there. Otherwise, post your question here and someone will try to help.
