Get your taxes done using TurboTax

@nocilor You never enter a dependent's income on your own tax return.   That means you do not include a dependent teenager's W-2 on your own tax return nor do you include your elderly parent's income on your own return.  If your mother had enough taxable income to file a return, then she could file her own return and say that she can be claimed as someone else's dependent.  You say she only had $2100 of income.  That is such a small amount of income that she would not owe any tax on it, so she does not need to file.  Her income does not go on your tax return.
