Independent Contractor - Married Filing Jointly

Hi! I started work this year as an Independent Contractor using an EIN and a 1099. I will be filing taxes jointly with my spouse, who has regular IRS withholdings taken out of his paycheck through his W-4. Do I need to make quarterly tax payments or does my spouse's contributions count for the both to avoid an underpayment penalty? Could/should we boost his withholding amount to potentially cover my taxes due? Thank you!!!
