Retirement tax questions

Does trustee send a form to prove that I repaid 1/3 this year?

I left the employer whose 401K that I withdrew from. Since then, I rolled over to Vanguard. It seems like I can send 1/3 to Vanguard & tell them it's a repayment. Question is: will Vanguard report to IRS that I repaid? Will I get a proof also?
