Sounds like you using Photoshop and not Photoshop Elements.

Anyhow Jpeg only supports file sizes of up to 2 gb and photoshop cc (version 13)

and older 30,000 px x 30,000 px pixels dimensions while photoshop cc (version 13.1) allow

about 64k (61,000 px in either direction)

You might try flattening your document before saving and see jpeg is available.

The TIFF file format supports up to 4 gb file size if that is an acceptable file format for the Flex Printing shop.

PSB is the Large Document Format in photoshop cc.
