The problem with ASDM is it's hard to explain how to do things like this, but I'll give it a shot.
Click "Configuration" in top left
Select "Firewall" in bottom left
Select "Access Rules" in left pane
Locate the ACL "outside_access_in" in the main window. Select that ACL
Click "Add" / "Add Access Rule"
Select the appropriate interface
Change destination to 1.1.1.1
Change the service to https, it should find tcp/https
Click OK
You should see the new entry in the main window
Next, select "NAT" in the left pane
Select the interface the NAT will be applied on
Select "Add" / "Add static NAT Rule"
Enter the source and destination addresses
Click the box to enable PAT
Select TCP
Enter HTTPS in both lines
Click OK
That should about do it. One of the things you might do, though, if you're comfortable at the CLI, is enter the commands via CLI, then look in ASDM to see what the ASDM window looks like when it's pulled in the commands you entered.
