First, it's important to point out you are not asking the QB Community. They are at this other link:

Next, it matters how you entered Sales.

"Would I need to make a journal entry and credit the sales tax liability account and debit the checking account to properly match the transaction?"

We assume you are asking about the client making their retail collections payment out to the taxing authority, after selling to customers.

Sales is:

Debit Bank

Credit income

Credit Sales Tax Liability

Or, using Sales Receipt, in QB, with taxable status set correctly.

If using QB for this, the Sales Tax Function takes care of everything; you never use JE or regular banking for making the entry for sales tax liability.

But, if you are manually posting Income and Liability, then the banking is a Deposit with the Splits: income and sales tax liability. The Check Expense entry has that same Liability account for the payout of sales taxes and a check is a Debit to the target account (Sales Tax Liability) and a Credit for the source (checking).

If you are doing this for a client, working in their QB file, never use JE in the same account as their own Sales Tax Liability would be managed by the program. Any method you are using other than the provided function will be orphaning the sales tax reporting and tracking that the program wants to do for them. Don't make their ability to manage their data worse. Use your own Liability account for your manual method for clearing, in other words.

If you are simply working off of the bank statement, you don't have any info as to liability owe and paid from any prior period, and no info for separation of the deposit income from the deposited sales tax collections. That means you might be putting all deposits to income and the sales tax payment would be expense; it's not really right, but you have to manage with the data you have.
