I gave 10 different times to goodwill and listed my items on its deductible each donation is worth less than $600, totals to a sum of $6,000 what can I list on my 1040?

I list each group of donations on its deductible, then go to goodwill and get donate and get a receipt in return.  Each group of donated items is less than $600.  The total for the year is approx 7,000.  How much can I claim on my tax return?  My taxable income is approximately $130,000,
