1099 help

Hello im new to this forum and would like help and feedback from others i have done some searching on this forum but havent found a clear answer. Ok I was a 1099 Trucker for like 3 months out of 2018 and im filing my own tax return to try and save because i know i will have to pay. Im using freetaxusa.com and while filing out info it asks i get to the DOT meal allowance it asks for total price meals paid for 2018 and upon further research i came across $63 per day allowance. No meals where reimbursed by owner of the company but I would not come near $63 per day just breakfast and lunch and a few snacks before hitting the rack. I suppose irs considera meals as being something like paying for breakfast and lunch I would like to say snacks as well but im thinking no. So in claiming the DOT meal allowance do i add up all meals paid for while away from home and since i dont have reciepts or not all of them will irs accept bank statements if i get an audit or what are the possibilities of an audit...

 

Ok so there is no need for me to go over bank statements and add up all my meals I had during the time i been away?? I was a team driver west coast to east coast gone for 5-6 days and off for 34 hours and back on the road again. So what about if i didnt even spend $63 per day on meals should i still multiply $63 by the number of days i been away from home?

 

On the questions asked it asks both DOT meals and there is also the standard meal deductions what do i use.... according to IRS pubs I would be under the DOT meals since im away for 24 hours or longer please correct me if i am wrong
