iPhone iTunes Backup Disappeared; Phone reset to factory settings

recently, reset iphone (7, ios 11.2.1) factory settings, when documents & data size starts getting crazy. usual, made backup before reformatting device. however, my backup disappeared. not on itunes, or anywhere in laptop. in case, reason, backup never made, tried running recovery softwares find any of old files, no such luck. ran five recovery softwares already.

there still way me data back? thanks!

(edit)
seems i've overwritten files. accident, after factory reset, loaded old backup onto phone. when realised happened, reset phone again, time setting new phone. no longer optimistic files can still recovered. instead, i'd know setting should've used after reset could've still retrieved data?)

(ps: yes, i've tried googling , youtubing problem, none of solutions, e.g., recovery software, manually looking folders, turned results.)

 

do use tm? if can recover files. if not laptop backup? should bale recover there.
