If I use my car to deliver food for Grub hub, how would I calculate the actual expenses used for my car if I didn't save all receipts to know specifically?

You may be able to find helpful details in your credit card and bank statements.  Please see the TurboTax blog A Guide for Self-Employed Filers that Haven’t Tracked Their Expenses This Year for more information.

If you can reconstruct at least a partial log of some of your vehicle expenses paid during the year, you can take a deduction related to these. Just keep this reconstructed log with your tax files for future reference.

If you don't know what your expenses were, you won't be able to claim a deduction.

The IRS requires that you keep adequate records or provide sufficient evidence to support the miles you've driven for your business.
