Overcontribution to Roth IRA

I over contributed to Roth IRA in July 2024 by $7000 and now while filing for taxes using turbo tax realize this.  I am working on withdrawing excess contributions plus any earnigns from my brokerage account as of today, April 7 knowing deadline for taxes is April 15!

Have few questions:

1. Do I wait to complete my taxes till that money is withdrawn from my Roth IRA?

2. I see I need to fill 1099-R.  If I can't get this form in time from my brokerage, how do I go about it with filling my taxes?

3. If I do fill for 1099-R then what do I need to put for my Roth IRA contribution while file my taxes as it is my only contribution to my Roth IRA for 2024. 

4. If there proper steps that I need to take?
