how do I change my auto lock on my screen so it doesn't go dark after 1 minute.

1. On your Mac, choose Apple menu  > System Preferences, then click Battery.
2. Do any of the following:

• Set your Mac to go to sleep and wake up at a specific time: Click Schedule, then select the options you want to use.
  • See Schedule your Mac notebook to turn on or off.
  • Switch between graphics modes: Click Battery or Power Adapter, then select “Automatic graphics switching” to switch between graphics modes automatically for better battery life.
  • Set sleep times for when you’re using your Mac notebook’s battery: Click Battery, then drag the “Turn display off after” slider.
  • Set sleep times for when you’re using your Mac notebook’s power adapter: Click Power Adapter, then drag the “Turn display off after” slider.
  • Keep your Mac from going to sleep automatically: Click Power Adapter, then select “Prevent computer from sleeping automatically when the display is off.”
  • Put hard disks to sleep: Click Battery or Power Adapter, then select “Put hard disks to sleep when possible.”
  • Keep your display dimmed while using your battery: Click Battery, then select “Slightly dim the display while on battery power.”
• Update your system while it’s asleep: Click Battery, then select “Enable Power Nap while on battery power.” Click Power Adapter, then select “Enable Power Nap while plugged in to a power adapter.”
  • See What is Power Nap?
• Allow your Mac to wake briefly so users can access shared services (if applicable): Click Power Adapter, then select any of the available “Wake for…” options, such as “Wake for network access.”
  • See Share your Mac resources when it’s in sleep.

If your screen goes dark automatically with you doing nothing then move the slider in the System/Energy Saver preference pane to whatever time you want to have the screen go dark if there's no activity on the Mac. I have mine set to 10 minutes:

In the System/Energy Saver preference pane with this slider:

My apologies! I edited my post.

If you are using Control Command Q to lock the screen— there is no over ride for the screen going b̶a̶l̶c̶k̶ black.
