Pls what do I do for a jamb regularization with a misspelt in surname..

I actually applied for jamb regularization in 2015 and when the number will be out my surname was spelt wrongly while my first name was initialised...
And I have submitted the jamb number to school for upload on Senate list which had been done successfully..

I have applied for correction of Names since 2020 but it's yet to be effective...
What can I do??
Is it advisable to do a fresh regularization or not
