@krishnan-success21 , for Tax Year 2024
1. you would still be a Non-Resident Alien and therefore taxed ONLY on US sourced income.
2. Because your first day in the country ( absent any other visits etc. ) is not Jan 1st 2024, you would not be able to use standard deduction. This means there is no advantage by including your spouse and child on your return ( if you chose to be treated as a resident for tax purposes, were taxed on your world income etc.
Thus you should file as a Non-Resident, be taxed ONLY on US sourced income using form 1040-NR ( not supported by TurboTax ( use tax professional, on-line like SprinTax or similar ).
For Tax year 2025, you will pass the SPT ( Substantial Presence Test ), you should consider your wife + child as dependents ( unless she moves to US, in which case you should be able to file as MFJ -- Married Filing Joint.
Is there more I can dol for you ?
Namaste ji
