One can't just take it upon themselves to do a tax return for another, even if they're deceased. Things have to be worked through the courts and a personal representative has to be legally recognized or appointed by the court. Then, and only then, can the personal representative do things such as file tax returns on the behalf of the deceased.
Even if you Uncle left a Last Will & Testament appointing you as his representative or administrator of his estate, that document has to be filed with the courts and run through the legal probate process before you or anyone else can act on the instructions of the will.
Evidently you can file even if not court appointed, since Form 1310 accommodates this scenario.
While that's true, it can create issues and problems if later a court appointed or recognized administrator of the estate wants to make it a problem or issue. Especially if the IRS finds issues with the return.

Please see this TurboTax tips article and this help article for more details regarding filing a return for a deceased person. In the Personal info section of TurboTax, a question appears asking if the person for whom the return is being filed has died.
Upon the death of a taxpayer, a new taxpaying entity—the taxpayer's estate—is born to make sure no taxable income falls through the cracks. Generally, income is taxed either:
The filing of the deceased taxpayer's final return usually falls to the executor or administrator of the estate, but if neither is named, then the task needs to be taken over by a survivor of the deceased. The final return is filed on the same form that would have been used if the taxpayer were still alive, but "Deceased:" will appear at the top of the return followed by the person's name and the date of death. The deadline to file a final return is the tax filing deadline of the year following the taxpayer's death.
The filing requirements that apply to individuals will determine if the personal representative must prepare a final individual income tax return for the decedent. If the deceased had no income at all besides Social Security, then they would not be required to file.
The personal representative of an estate is an executor, administrator, or anyone else in charge of the decedent's property. The personal representative is responsible for filing any final individual income tax return(s) and the estate tax return of the decedent when due.
If a return is required, it can be prepared in TurboTax. Please see this TurboTax tips article and this help article for more details regarding filing a return for a deceased person.
