Hello keht,
Yes, you can still delete the direct deposit paycheck to do corrections. Deleting the direct deposit paychecks will stop or cancel the submission process. Make sure you do it on or before 5PM Pacific time, two banking days before the paycheck date.
Since you've mentioned that the paycheck date will be on Friday, you can still delete it today or before 5PM Pacific time on Wednesday.

Afterwards, you can recreate the paychecks with the correct details and submit them again.
Keep us posted if you require additional help with this. Have a great day!
