Why are you trying to enter how much you spent on groceries? Are you in a state with a credit of some sort for groceries?
If you are trying to use sales tax you could just use the Easy Guide for sales tax since you do not have your actual receipts. The software will use a formula based on your filing status and income, number of dependents etc to calculate a sales tax deduction for you.
And.. is you do not have enough other itemized deductions like mortgage interest, medical expenses, charity donations....entering sales tax will have no effect on your refund or tax due. Sales tax is an itemized deduction.
Your itemized deductions have to be more than your standard deduction before you will see a change in your tax owed or tax refund. The deductions you enter do not necessarily count “dollar for dollar;” many of them are subject to meeting tough thresholds—medical expenses, for example, must meet a threshold that is pretty hard to reach. (Only the amount that is MORE than 7.5% of your AGI counts) The software program uses all the IRS rules that apply to the expenses you enter, and it tells you if you have enough to use your itemized deductions or if using the standard deduction is more advantageous for you. Under the tax laws that have been in effect since 2018, some deductions have been capped—there is a $10,000 limit to the itemized deductions for state, local, property and sales taxes.
The standard deduction makes some of your income “tax free.” It is not a refund. You will see your standard or itemized deduction amount on line 12 of your 2024 Form 1040.
