Short answer
A TSP annuity is a purchase, not a normal withdrawal.
The TSP lets separated participants use money for a life annuity, but the TSP frames that as different from keeping money in the account and taking installment or partial withdrawals. Timing, survivor features, interest rates, and control of the balance all matter.

What you actually came to find out
Plain answers first. Sources stay below for checking details.
What is the TSP annuity option?
The TSP annuity option uses TSP money to buy life annuity payments through the TSP annuity provider.
Is it the same as installments?
No. TSP installment withdrawals keep money in the account. A life annuity converts money into contract payments.
What timing matters?
The relevant timing is when the worker separates, when income is needed, and when the annuity purchase is made.
What changes for a spouse?
Survivor features can change the payment and the protection for the person who outlives the other. The exact contract option matters.
