Saver's Credit not calculating with SEP IRA contribution but does for regular IRA contribution

I originally entered my IRA contribution as a traditional IRA contribution, and Turbo Tax calculated and gave me the Saver's Credit. When I deleted that entry and entered the same amount as a SEP IRA contribution instead, Turbo Tax does not calculate the Saver's Credit.  What am I doing wrong? Technically, tax savings and the Saver's Credit amounts should be the same whether it's a SEP IRA or a traditional IRA contribution, right?
