So you have used up all four primary partitions available, making the
fourth the container for extended partitions. You've then proceeded to
allocate most of your 15 possible partitions.

Yeah, you're trying to create it as a primary partition, but you
already have used up all those slots.

man fdisk

It'll tell you most of what you need to know.

Create the partition as an extended partition, instead of primary partition.
