You should find the feats named like this: Strixhaven Initiate (Lorehold - Intelligence), where the middle element is the Strixhaven college name, and the last part is what spellcasting modifier you'll use for the spells.
If you're still not finding any feats under Manage Feats whose names start with "Strixhaven Initiate", then try these things:
Make sure you have Magic The Gathering Content enabled (red/right) in your HOME | Preferences - I assume you do already, but check just in case it got toggled off.
Try bumping your character up 1 level and then back down; this will "wake up" the character sheet, which could make the feats appear in Manage Feats.
You may need to request the campaign's Content Sharing be turned off and back on again.
Make sure that your Entitlements are synced. Your DM and/or person who owns Strixhaven may need to check their own entitlements.
