Duplicate Transactions in Bank Register

I am a QB student and I am 3.5 weeks away from concluding the semester and I am not able to move on until this gets fixed. I am running out of time. I made calculations manually and if I can figure this out then I will have the correct balance. My balance needs to be $46,955.73 but currently is $46,432.73. I have 3 duplicate transactions that if I delete 1 the duplicate deletes as well. I need help figuring out how to delete the duplicates without deleting the deposits I do need. Those are the transactions for $75, $95 and $353 which totals to $523. That added to my current balance of $46,432.73 will give me my required total of $46,955.73. Please help me.
