Retirement tax questions

The lady i was on the phone was helping me because at first I was supposed to receive $5k after doing it correctly before entrusting an agent and received credits. However I accidentally did it as mail rather than electronically to my bank. The lady guided me but did an error making me click remove my son and I requested to start completely over so I can do it the right way and in the end put it as electronically not paper. Now I owe because of that error from that agent after she said it is "normal" "it says i owe $700+ but it'll send the $5k+ i was suppose to get and deduct the $700+ i owe" i said okay and filed and now I owe which is cruel!
