Based upon the fact pattern of the question, you have filed Married Filing Jointly ("MFJ"), but potentially are moving in 2025 to Married Filing Separately ("MFS") , and none of the three W-4s (two for you and one for your husband) have ever been updated. For visibility this is the W-4
Whether you choose to continue filing as MFJ or move to MFS you want to fill out Multiple Jobs Worksheet. You can also use this calculator: W-4 Calculator
Keep in mind that in Step 3 of the Multiple Jobs Worksheet you need to adjust the pay periods in Step 3 by the remaining pay periods for 2025, since we are five months into the year.
All the best,
