Estimated Tax Roth Conversion and Charitable Carryover

I converted about $1600 into a Roth in April 2024. I just found out that I should have paid estimated tax on this in quarterly deadlines. Well, I didn't work in 2024 until May and the new job pays taxes from my wages. I will make about 23,000 in 2024 in income but I have a charitable carryover of about $12,500 that will reduce my income. I will be in the 10% tax bracket.

 

1) Is it possible that the income tax from my pay can cover my Roth contribution estimated tax and that I would not have a penalty of any underpayment?

 

2) Or, should I be trying to pay the estimated tax (10% of $1600 being $160) on the Roth conversion on the IRS website?

 

3) Also, can I divide up my charitable carryover or do I have to use it all up this year since it's less than my gross income?

 

Thank you!
