Get your taxes done using TurboTax

Thanks for the responses to my follow-up questions. Re: the 2nd one, it’s still unclear to me how I would report any int/div/rental income the estate would receive Jan 1-Jul 31,2025. For the initial 1041, by selecting a fiscal year that runs Aug 1,2024-Jul 31,2025, the return is due by Nov 15,2025. At such time any 2025 1099s reported under the estate EIN would not be generated until early 2026, so how would I report the 7 months worth of int/div/rental income that’s part of the “2024 fiscal year”? I can calculate using monthly bank/brokerage/

property manager statements for Jan 1-Jul 31,2025, but not based on any 1099s. Specifically, a) is there a line on 1041 to report this income based on calculations, or b) do I request an extension, or c) do I submit the return on time and then amend when I finally get the 1099s? 
Thanks for your quick response and continued guidance!
