I am sorry for your loss.
Frankly, I have to suggest that you consult with legal and tax professionals if you have no experience in matters such as the one presented, particularly if there are other beneficiaries involved.
If you want to try and handle the 1041 yourself, then you need to purchase TurboTax Business, which must be installed and run in a Windows environment. In the process of preparing the 1041, a (presumably final) K-1 will be generated for each beneficiary which will contain each beneficiary's share of income, gain, loss, deductions, credits, et al. Each beneficiary will then enter the information from the K-1 into their individual income tax returns (1040).
You should confirm with the bank that there will be no income (in the form of interest, most likely) that will accrue to the estate. If not, then the bank is simply distributing principal which does not need to be reported to the IRS.
If your father only had two accounts, a bank account and an account at an investment firm, then it is likely you will only have to be concerned with the 1099 (1099-B, most likely) that you receive from the investment firm.
There is no need to "close" the EIN the estate was issued; you will mark the 1041 as "final" after all of the assets have been distributed.
