Where can I access old 1099 forms

If you lost your forms, you can try to contact the issuer. 

Other options include:

• Order a full copy of your return from the IRS for $50, which will also include your W-2.
• Wage and income transcripts are available from the IRS free of charge. 
• They're not exact copies, but they contain everything on your W-2 except the state and local information
