030126DC is the Elder Scroll (Dragon) from Dawnguard. If you're not doing the DLC quest, then you're not going to have that version in your inventory.

The item ID for the original Elder Scroll that is used in the (Non-DLC) main quest is 0002D513.

If you haven't finished the main quest yet, why do you want to remove it from your inventory? After you finish the main quest you can sell it to Urag gro-Shub or keep it for when you start Dawnguard.
