8086 or 8606?
What else?
You don't normally enter a 8606 itself. It is automatically created when:
1) You make a new non-deductible Traditional IRA contribution.
2) You take a distribution from a IRA that has a after-tax "basis".
3) You make a conversion of a retirement account to a Roth IRA
If none of those occurred, then the last filed 8606 remains in effect
