doesn’t matter what you put down, you choose when you turn in your winning ticket at the lotto offices… for sums that large there is a lot of paperwork, tax forms ect..
bring an accountant or a tax lawyer.
The Mega ticket slip does not give you an option of lump sum or annual payments for 26 years. The California Super Lottery gives you a choice.
You choose the option when you claim the prize. It is a nice problem to have.
i agree with jb, bring an accountant or a lawyer
