You would do it like this:

path = "C:\\Users\\User\\AppData\\Local\\Programs\\Python\\Python38\\Stack overflow\\textfile.txt"
newpath = "C:\\Users\\User\\AppData\\Local\\Programs\\Python\\Python38\\Stack overflow\\textfileout.txt"
text = open(path, "r")
textinfo = text.readlines()
dictofinfo = {}
for line in textinfo:
  line = line.strip()
  lineaslist = line.split(" ")
  name = lineaslist[0]
  if not(name in dictofinfo.keys()):
    dictofinfo[lineaslist[0]] = [lineaslist[1:]]
  else:
    dictofinfo[lineaslist[0]].append(lineaslist[1:])
text.close()

out = open(newpath, "w")
for entry in dictofinfo:
  totaltobepayed = 0
  out.write(entry   "\n")
  for seperateentry in dictofinfo[entry]:
    totaltobepayed  = int(seperateentry[2])
    out.write(" ".join(seperateentry)   "\n")
  out.write(str(totaltobepayed)   "\n")
out.close()
