suspense and correction error

Hi My Dear Tutor, I know i ask lots of questions but it is important for me.

Samantha has extracted a trial balance and created a suspense account with a credit balance of $759 to make itbalance.Samantha found the following:

1. A sales invoice for $4,569 has not been entered in the accounting records

2. A payment of $1,512 has been posted correctly to the payables control account but no other entryhas been made.

3. A credit sale of $131 has only been credited to the sales account.

What is the remaining balance on the suspense account after these errors have been corrected?
A $3,810 debit
B $2,140 credit
C $890 credit
D $622 debit

here is first is omitted which does not impact suspense account and understandable

3rd note it says only credited sales account and omitted trade receivable account and debit trade receivable account credit suspense account-131

2nd note seems to be confusing because it says a payment of $1,512 has been posted correctly to the payables control account but no other entryhas been made, meaning from my point of view debit purchase omitted and credit trade payable only recorded 1512.coming to its correction side, debit purchase-1512 and credit suspense account 1512.The answer says that debit suspense account?why?

I know payment to payables go to debit side of payable control account but in this case if we debit suspense account what its credit side will be?because its payable side is correctly recorded according to the given note.

this is what i think? but it is not correct.
did
debit omitted
credit payable-1512

should
debit purchase -1512
credit trade payable-1512

correction
debit purchase-1512
credit suspense account-1512
