dependent minor filing first tax return (QUESTIONS)

My son is a minor who needs to file his own tax return because he made over $16800 in 2024.  I can still on my tax return claim him as a dependent. My question is can he e-file his tax return being it is his first time e- filing without being rejected because he has no previous AGI to put on the return? Will the IRS accept the tax return with no previous AGI? He has no pin number either being this is his first time e-filing a tax return.
