Can I still send extra tax payments? I missed sending in 1040 ES payment voucher and would like to make tax payment to avoid an underpayment penalty next year.

Yes.  Pay as soon as possible.  Or you can pay directly on the IRS website https://www.irs.gov/payments

Be sure to pick the right kind of payment and year.....2024 Estimate

sorry for some reasom I thought you wer alking about estimates for Illinois. for fedeal basically the same rules apply for federal

 

 

depending on your 2024 Federal tax, you could still have a penalty for failure to make estimates the first 3 quarters.

 

if you have Federal withholding that could be increased for the year to make you penalty proof (100% of 2023 tax AGI less than $150K). even though the withholding would occur late in the year, under Federal law 1/4 of the total can be assumed to have been paid each period. This is not true with estimates. They only count on the date of payment.

correct no illinois mentioned. i was giving an example.  OP has multiple non-resident states. just showing that Turbotax may not handle state passive loss carryovers that differ from the federal
