If following case Test-statistic is a 2-sample Dependent (paired) t-test; what are the steps to undertake in SPSS?

The researchers were concerned that the observed Vitamin B12 levels would be higher in non-fasted individuals than fasted individuals.

To determine whether observed mean blood Vitamin B12 levels are elevated in a non-fasting state compared to a fasting state, the researchers recruited 20 participants. Each of the participants had their Vitamin B12 levels checked twice. On Day 1, Vitamin B12 levels were measured after fasting for 8 hours. On Day 2, Vitamin B12 levels were measured without prior fasting. Answer this research question using the 1% level of significance. Data below;
