Retirement tax questions

@DanaB27 Thank you. Couple of questions:

 

  1. What does "your plan allows it then you can leave the fund in the account." mean? In my situation, there was a change in employers and my total contribution amount across both employers was ~ $300 over the 2024 contribution limit. Do I still need to figure out if either plan allows that?
  2.  What does this part mean? "You can't include the excess amount in the cost of the contract even though you included it in your income."
  3. If I do not withdraw the excess contributions, should I expect any 1099 form this year or next? Also, does it increase the probability of an IRS audit?
  4. If I do decide to request withdrawal of excess funds from my current employer, how would they know if I over-contributed since the contribution through each employer was within the contribution limit?
