How can i bring my milage/ journey history over from my quickbooks self employed account?

Welcome and thanks for reaching out to the Community, @genesisprotectio.

You're referring to importing your mileage/journey history from QuickBooks Self-Employed (QBSE) to QuickBooks Online (QBO), correct? If so, this option is currently unavailable.

I'll pass along your suggestion to our Product Developers. They're always looking for ideas to consider on how to improve QBO. In the meantime, I recommend visiting our Blog site. This is where we share recent happenings and future developments, such as updates to newly added features.

Just in case, I'll add these articles for future reference:

• Track mileage in QuickBooks Online.
• Switch from QuickBooks Self-Employed to QuickBooks Online.

Reach out to me in the comment section below if you have any other questions or concerns. I'm always here to help. Have a good one!
