I Made a Mistake Calculating 1 Rep Max (5/3/1 Beginners)

so i made a mistake when calculating my 1rep max for 5/3/1 beginners on squats. typed way more than what i could do and went and did the first workout with the program and it was heavy. i did however finished everything else (i did bench with correct 1rep max). what should i do for the third workout of the first week? should i adjust to what its suppost to be and disregard the first workout for squat and continue? or go a bit lower in weights so next week workout will be = to this week? sorry for my english.

also should i eat less to maintain weight since this happened?
