Tax law changes

Thanks. Yeah, I am aware the K-1 for corporations etc. is the March 15 deadline and not what I am seeking. Again I am seeing a K-1 from a 1041 for a Trust/Estate. Also, I'm still reading if I owe taxes for the 2022 calendar year I still have to pay by April 18 which is the original overall tax deadline. How exactly can I pay what I might owe by April 18 if I don't what I will end up owing without all the forms etc. that are now not due until October?
