"The IRS will treat the child as the qualifying child of the parent with whom the child lived for the longer period in 2023." IRS January 23, 2024

Since you do not seem to want to ask a question, it is difficult to know your purpose in posting here or why you are complaining about updating the software.

Are you having some sort of issue to determine whether you---or someone else -- can claim a child?  

Are you the custodial parent?  Do you have an agreement with the other parent to allow the other parent to claim them--due to divorce or that you live apart and share custody?  Did one of you sign a Form 8332?

If there is a signed 8332 then the custodial parent retains the right to file as Head of Household, get earned income credit and the childcare credit.  The non-custodial parent gets the child tax credit for children under the age of 17.

As far as the IRS is concerned, the custodial parent is the one with whom the child spent the most nights during the tax year--at least 183 nights.

If you are a non-married couple who live together then only one of you can claim the child(ren) and the one not claiming the child does not enter anything at all on their tax return about the child. 

If this does not help, then please ask a clear, complete, specific question.
