How to handle extra 401K over contribution through tubotax?

I over contributed about $1000 over the $19500 401K limit in 2021 as I changed my employer. My current employer had 15th March as last date to notify their 401K handlers (Vanguard) which I missed. Today is 8th April and even though I will notify my employer to return the excess contribution, it may not happen by 15 April. I called Vanguard today and they are saying they cannot do anything now and suggested I talk to a tax expert. 

 

What options do I have in turbo tax to fix this situation if my employer is not able to return that extra contribution, their matching contribution, and any possible income generated on that extra contribution? Should I go to a tax expert to file my tax this year to help with this situation?
