I wouldn't worry about it that much
@Little My , just don't take your levemir dose this evening.
I would bolus for the carbs you've eaten, the extra levemir won't be doing anything to deal with that.
You'll have a bit of an overlap with the levemir this afternoon/evening. So watch out for hypos and maybe think about reducing your dinner time bolus.
But the overlap should have finished by bedtime, if you omit your usual pm basal dose. You might wake up a little high cos levemirs lasts 12 hrs, so you'll have no basal by about 5am but if you wake up early to start fresh tomorrow that'll be easily dealt with
