how to enter withdraw profit?

First check with the state to find out how often a shareholder meeting is required, yes even if there in one shareholder.  That meeting must be recorded on paper, and it is where the shareholders vote on issuing a distribution of profit.

If that is to be done, the total amount is moved from retained earnings to an account called distribution payable (you will have to create it the first time, a liability account).  Then on the date of distribution checks are written for the amount to each shareholder and you use the distribution payable account as the expense (reason) for the check

Hi fd_com,

I'll guide you on how to record the distribution of profit in QuickBooks. First off, you'll need to set up an owner's draw account. Then, write a check from an owner's draw account. 

Here's how:

1. Go to the Lists menu, then select Chart of Accounts or press CTRL + A on your keyboard.
2. At the bottom left choose Account, then click New.
3. Select Equity, then click Continue.
4. Enter the account name (Owner's Draw is recommended) and description.
5. Click Save & Close.

Once done, go to the Banking menu to write a check. Here's how:

1. in the Write Checks window, go to the Pay to the order of section. 
2. Select the owner, and enter an amount next to the $ sign.
3. Enter the amount of the check to the equity account you created to record the owner's draws, then click Save & Close to record the check.

For more insights about the owner's draw account, refer to this article: Set up and pay an owner's draw.

I also recommend consulting your accountant to make sure your books are accurate.
